I have to interrupt you right there. On a championship team, defense and goaltending can't just be passable. They need to be strengths in and of themselves so you can win multiple play styles vs multiple opponents.
A stronger defense also allows for your offense to be used differently and more aggressively, whether that's a better transition game or more freedom to counter punch without worrying that your D have no idea how to defend a 3 on 2 or a 2 on 1.
Goaltending needs to be a strength in and of itself because you know you can retreat into a shell game with confidence.
Strength begets strength. You can't go cheap on everything else because those weaknesses always short circuit the offense. Every year, the opposition beats us on a hot goalie, park the bus variation and some form of physical play. Why we consistently ignore these issues with the fantasy we'll outscore our opponents is beyond me.
